I saw the same article mate, as far a i know he can't cause of PL rules.. "In the Premier League, players on loan are not permitted to play against the team which holds their registration (section 7.2 of rule M.6). This means that one of the 'big' clubs can loan out a promising young player to an opposing team in the Premiership but the loanee will not be allowed to play against his 'owning' club and his parent club will not be able to observe how he plays against a 'big' club. Loanees are, however, allowed to play against their 'owning' clubs in cup competitions, unless they have played for their owning club in that cup during that season."
